Pakistani security officials say a suspected U.S. drone has crashed in northwestern Pakistan near the Afghan border.

The officials say the unmanned drone crashed near the village of Jangara in the South Waziristan tribal area.

Members of the Taliban militia say they have recovered the debris from the crash.

It is not clear what caused the crash.

The U.S. Embassy in Pakistan has not commented on the incident.

American officials normally do not comment on the U.S. drone program in Pakistan, which is operated by the CIA and has been used to carry out aerial strikes against suspected Taliban and Al-Qaeda sites in northwest Pakistan.
